eth: fbnic: Collect packet statistics for XDP

Browse source

Add support for XDP statistics collection and reporting via rtnl_link
and netdev_queue API.

For XDP programs without frags support, fbnic requires MTU to be less
than the HDS threshold. If an over-sized frame is received, the frame
is dropped and recorded as rx_length_errors reported via ip stats to
highlight that this is an error.
